Swift MongoKitten：按生成的字段排序

我试图在MongoKitten中创建以下mongo语句，这是一个swift框架

db.pages.find( {$and: [{$text: {$search: "ebay"}} , {"lang" : "en"} ] }, {score: {$meta: "textScore"}}).sort({score:{$meta:"textScore"}})

在swift中，我有以下内容，但我无法按照生成的字段得分对其进行排序

let query: Query = [
            "$text": ["$search": "ebay" ],
            "lang" : ["$eq": "en"],
        ]

let projection: Projection = [
             "_id": .excluded,
            "url": "url",
            "$score": ["$meta" : "textScore"]
        ]

let sort : Sort = [
            "score": .descending
        ]

        let matchingEntities: CollectionSlice<Document> = try pages.find(query, sortedBy: sort, projecting: projection)

让查询：查询=[
“$text”：[“$search”：“ebay”]，
“lang”：[“$eq”：“en”]，
]
let projection:projection=[
“_id”：。排除在外，
“url”：“url”，
“$score”：[“$meta”：“textScore”]
]
让排序：排序=[
“分数”：。递减
]
让matchingEntities:CollectionSlice=try pages.find（查询，排序依据：排序，投影：投影）

---

有人做过类似的事情吗？

尝试使用自定义的

排序器

let query: Query = [
            "$text": ["$search": "ebay" ],
            "lang" : ["$eq": "en"]
]
let projection: Projection = [
            "_id": .excluded,
            "url": "url",
            "score": ["$meta" : "textScore"]
]
let sort : Sort = [
            "score": .custom(["$meta" : "textScore"])
]
let matchingEntities: CollectionSlice<Document> = try pages.find(query, sortedBy: sort, projecting: projection)

让查询：查询=[
“$text”：[“$search”：“ebay”]，
“lang”：[“$eq”：“en”]
]
let projection:projection=[
“_id”：。排除在外，
“url”：“url”，
“分数”：[“$meta”：“文本分数”]
]
让排序：排序=[
“分数”：.custom（[“$meta”：“textScore”]）
]
让matchingEntities:CollectionSlice=try pages.find（查询，排序依据：排序，投影：投影）
